If All Else Fails

Frequently hum in home theater systems is caused by a grounding problem with the cable TV system. Contact your cable provider if necessary to make sure the cable feed into your house is properly grounded. There are cable isolation devices available such as the Video Link #634 or the Mondial Magic specifically designed to cure this problem. In rack mounted systems, ground loops and hum can sometimes develop via the metal rack rails of the equipment rack. This problem can be solved with nylon shoulder washers available from Middle Atlantic Products (refer to rack mounting section of this manual).

Call your Parasound dealer or Parasound Technical Service. We can suggest other diagnostic tests you can easily perform. If we determine that your amplifier should be returned to Parasound or an Authorized Parasound Warranty Center for inspection and possible servicing, call for the location of a warranty center near you. If you choose to send it to Parasound, contact us to obtain a Return Authorization (RA) number. You will be asked to repack the unit in its original packaging plus an additional outer box for protection during transit. The Return Authorization number must be clearly marked on the outer carton only. You should ship the unit by UPS with adequate insurance. You must also include a copy of your purchase receipt to validate your ownership.

Units that arrive without your specific Return Authorization number, without a suitable shipping carton or evidence of improper internal packing must be refused. We do not accept collect shipments. After repair under warranty, the unit will be returned to you via prepaid UPS. In the case of an out of warranty repair, contact us and we will advise you of the repair charges before you ship the unit to us. The same packing and Return Authorization requirements apply.
